Liujiang basin is an important water source area of Qinhuangdao city. The surface collapse will happen at hidden karst areas, due to much exploiting of ground-water. The characteristics of hidden fault structure, distribution and water-bearing nature of Quaternary loose sediment, and distribution of surficial and hidden karst area are studied by means of multi-temporal and multispectral satellite images and aerial color photos and digital image processing technique, combining with comprehensive analysis of the data from ground truth investigation, geophysical prospecting and drilling. Accordillg to analysis of tile various geological factors which can cause surface collapse, the positions of dangerous areas of surface collapse caused by exploiting of grouod -water have been predicted.The reliable geological evidences also have been provided for preventing work.
